Motive / Inspiration

The evolution of Retrieval-Augmented Generation (RAG) systems has reached a pivotal point where traditional approaches are being enhanced with agentic capabilities. As AI systems become more sophisticated, the need for intelligent, autonomous RAG systems that can reason, plan, and adapt their retrieval strategies has become critical. This exploration was driven by the growing demand for more context-aware and dynamically adaptive AI applications in enterprise environments.

What I Built / Explored

Agentic RAG Architecture

Developed and demonstrated a comprehensive Agentic RAG system that goes beyond simple retrieval-generation patterns:

  • Intelligent Query Analysis: Agents that can decompose complex queries into sub-questions
  • Dynamic Retrieval Strategy: Multi-modal retrieval approaches based on query complexity
  • Context-Aware Generation: Enhanced generation with temporal and semantic context understanding
  • Feedback Loop Integration: Self-improving mechanisms based on response quality assessment

Key Components Implemented

  • Multi-agent coordination for parallel information gathering
  • Adaptive retrieval ranking based on query intent
  • Dynamic context window management
  • Quality assessment and response refinement loops

Technical Highlights

Advanced RAG Techniques

  • Hierarchical Retrieval: Multi-level document chunking and retrieval strategies
  • Semantic Routing: Intelligent routing of queries to appropriate knowledge bases
  • Context Compression: Advanced techniques for managing large context windows
  • Cross-Modal Integration: Combining text, structured data, and metadata retrieval

Implementation Stack

  • Azure AI Services: GPT-4, Azure Cognitive Search, Azure AI Studio
  • Vector Databases: Azure Cosmos DB for MongoDB vCore, Pinecone
  • Orchestration: LangChain, Semantic Kernel for agent coordination
  • Evaluation Frameworks: Custom metrics for retrieval quality and generation accuracy

Innovation Areas

  • Self-reflective agents that can critique and improve their own responses
  • Multi-step reasoning with intermediate verification
  • Dynamic knowledge graph construction from retrieved content
  • Real-time adaptation based on user feedback patterns
